Batman has arguably the best rogues gallery in comics. The Joker, Two-Face, Mr. Freeze, Scarecrow, Catwoman, the list of villains who call Gotham City home is epic. Even the more obscure Batman villains are formidable in their own right and don't get nearly as much credit as they deserve.
Due to the sheer volume of supervillains Batman has faced over his 75 year history, some of his most dangerous and interesting foes have been lost in the shuffle. It's time to give some of these lost bad guys their dues. Because anybody with the nerve to take on Batman has earned our respect, even the Condiment King. No, you know what, especially the Condiment King.
Name: Professor Hugo Strange
Abilities: Genius-level intellect. Master of psychology, chemistry, and biology.
Menace Rating: 8 out of 10 Mad Scientist Clichés
Okay, you know the one villain that's an evil psychiatrist who manipulates people to do his bidding? Or the evil chemist who creates a potent fear-inducing powder? Or the mad scientist who uses injections to turn men into hulking monsters? Alright, so merge all three of those and you get Hugo Strange. Three Batman villains in one and to top it off he knows that Batman is Bruce Wayne! It's astounding that Strange hasn't been featured in the DC Cinematic Universe yet.
Name: Professor Pyg
Abilities: Chemistry expert, preternaturally skilled surgeon.
Menace Rating: 6 out of 10 "DEAR GOD, WHAT DID YOU DO TO MY FACE?!?"
Professor Pyg just wants to make you perfect, that's all. Totally harmless, admirable even. Oh, except by "perfect" he means "lobotomized to follow his will through brain surgery, genital mutilation, mind-altering drugs, and a creepy doll mask permanently attached to your face."
With his army of "perfected" Dollotrons and the rest of his "Circus of Strange," Pyg is a psychotic menace to the people of Gotham. Despite being a relatively new villain to Batman's rogues gallery, Pyg has cemented himself as one of the most disturbing villains in the Dark Knight's lore. Now that's really saying something. It's like being the most stoned person at a Phish concert.
Abilities: You know what Batman can do? All of that but, like, EVIL.
Menace Rating: 10 out of 10 Doppelgängers
Owlman is the criminal genius version of Batman from Earth 3. He has the intellect, wealth, and martial arts abilities of Batman, but he is willing to kill and betray anyone or anything that stands in his way. If there is anything more dangerous than Batman, it's Batman without a moral compass. Or maybe Batman if he was also a shark, somehow. Get on it, DC writers.
Name: Cornelius Stirk
Abilities: Can make other people see him as someone else. Also eats human hearts, since you weren't having enough nightmares.
Menace Rating: 6 out of 10 Uneaten Hearts
Cornelius Stirk is a sick man. His delusions make him believe that he needs the nutrients of a human heart in order to stay alive. To add to this terrifying conviction, he believes that the heart is the most nutritious when it is full of norepinephrine, a natural hormone that secretes when a person is terrified. His ability to mentally make people perceive him as someone else allows him to get close to his victims for a quick kill and a hearty (heh) dinner. Luckily, Batman usually finds Stirk and returns him to Arkham Asylum, but Cornelius is still a sickeningly effective serial killer.
